(1998) Bradley, Peter; Rozenfeld, Anatoly; Lee, Kevin; Jamieson, Dana; Heiser, Gernot; Satoh, SJournal ArticleThe first results obtained using a SOI device for microdosimetry applications are presented. Microbeam and broadbeam spectroscopy methods are used for determining minority carrier lifetime and radiation damage constants. A spectroscopy model is presented which includes the majority of effects that impact spectral resolution. Charge collection statistics were found to substantially affect spectral resolution. Lateral diffusion effects significantly complicate charge collection

(1995) Heiser, Gernot; Altermatt, Peter; Williams, Angela-Margaret; Sproul, Alistair; Green, MartinConference PaperThis paper describes the use of three-dimensional (3D) device modelling for the optimisation of the rear contact geometry of high-efficiency silicon solar cells. We describe the techniques and models used as well as their limitations. Our approach is contrasted with previously published 3D studies of high-efficiency silicon solar cells. Results show that the optimum spacing is about 2/3 of that predicted by 2D simulations, and exhibits a much stronger dependence on contact spacing. The optimal value found is about 60% of that of the present UNSW PERL cells, however, the possible efficiency gain is only about 0.1% absolute.

(1995) Peng, Gang-Ding; Ye, A; Chu, PakJournal ArticleA novel technique for the fabrication of birefringent splittable composite (BISPEC) fiber is reported. We describe in details the design consideration, practical fabrication, and characterization of this fiber. The distinctive feature of this fiber is that the principal axes of the constituent fibers can be accurately aligned in the preform stage so that long lengths of well-aligned fiber can be drawn. We further demonstrate the application of this fiber by fabricating a polarization-maintaining coupler by simply introducing a local taper. Measurements show that such a coupler can have polarization extinction ratio as large as 31 dB (in the best case)
